OWASP Top 10 for Large Language Models

The OWASP Top 10 for Large Language Models is an authoritative guide published by the Open Web Application Security Project. It identifies the ten most critical security risks unique to LLM applications, such as Prompt Injection, Insecure Output Handling, and Sensitive Information Disclosure. While not a formal international standard, it provides actionable guidance for implementing frameworks like the NIST AI Risk Management Framework (AI 100-1) and upcoming standards like ISO/IEC 27090 (AI Security). In enterprise risk management, it serves as a crucial bridge, translating high-level regulatory requirements from the EU AI Act into testable technical controls, distinguishing these new vulnerabilities from traditional web application risks.

Enterprises can apply the OWASP LLM Top 10 in three practical steps. First, in 'Risk Identification & Mapping,' map the ten risks to all internal LLM applications and assess them within an ISO 31000 framework. Second, 'Implement Security Controls' based on the risk assessment. For 'LLM06: Sensitive Information Disclosure,' implement data masking and filtering to comply with GDPR Article 32. Third, 'Continuous Monitoring & Testing' involves automated scanning and red teaming to validate defenses. A financial institution that implemented this framework reduced AI-related security incidents by 40% within a year and successfully passed its annual ISO/IEC 27001 audit, demonstrating measurable benefits.

Taiwanese enterprises face three main challenges. First, a 'Lack of AI Security Talent,' as most security teams are unfamiliar with unique LLM attack vectors. The solution is to partner with external experts for customized training to build an internal champion team within three months. Second, 'Resource Constraints,' especially for SMEs. The solution is to start with open-source tools and prioritize the top three critical risks. Third, 'Complex Supply Chain Risk' from using third-party LLM APIs. The solution, aligned with ISO/IEC 27036, is to strengthen vendor management by requiring security reports like SOC 2 and defining security responsibilities in contracts.
